By using a SkyLink Receiver from ARRI you can quickly and easily upgrade all your existing SkyLink fixtures to support the LumenRadio CRMX wireless DMX protocol, including remote control via the SkyLink Base Station. This compact device attaches directly to the rear of the light using a 5-pin XLR connector, where it provides wireless DMX512 and RDM communication from ranges up to 1640' away. It is also very simple to install, as it features an integrated USB cable to receive power directly from the fixture instead of requiring a separate power supply.
